Question

Which of the following nuclear reactions will generate an isotope ?
(A) Neutron particle emission
(B) Positron emission
(C) $\alpha -$ particle emission
(D) $\beta -$ particle emission

Answer 1

Hint : To create a helpful measure of energy, nuclear fusion should happen in mass issues. What is required is to raise the temperature of the material until the particles have enough energy because of their warm movements alone to enter the coulomb hindrance. This cycle is called nuclear fusion. Thus, for nuclear fusion to occur, extraordinary states of temperature and weight are required, which are accessible just in the insides of stars including the sun.

Complete Answer
Isotopes have a similar number of protons however an alternate number of neutrons. Along these lines, neutron discharge will create an isotope. Then again, positron outflow, beta molecule discharge and alpha molecule emanation will change the nuclear number. Henceforth, they won't create an isotope. Nuclear fusion is a cycle wherein at least two lighter cores consolidate to frame a heavier core. The mass of the item is in every case not exactly the amount of the majority of the individual lighter nuclei. The combination cycle can be done distinctly at the amazingly high temperature of the request for ${10^7}K$ on the grounds that, just at these exceptionally high temperatures the cores can beat their common repugnance.
Thus, the correct answer is option A.

Additional Information
A reasonable assembly of deuteron and triton is masterminded at seeing the blast of the nuclear bomb. Ideal temperature starts the combination of lighter cores in an uncontrolled way. These deliveries are a colossal measure of warmth energy.

Note
Nuclear Fusion is a response through which at least two light cores crash into one another to shape a heavier core. This response happens with components that have a low nuclear number, for example, hydrogen. It is something contrary to atomic splitting response in which weighty components diffuse and structure lighter components. Both atomic combination and parting produce a huge measure of energy.
